The last ACKs that you mention are window update notifications that the client application removed data from the recieve buffer. The recieving application on the FreeBSD machine fell way behind the sender. When the recieving host lost a packet, the new data will go into the fragment reassembly area and not the socket. The recieving application starts to catch up. Strange this does not happen a lot. --Mark Tinguely
